Material reacting like carcinoembryonic antigen (CEA) in the radioimmunoassay has been extracted from rheumatoid synovial membranes. This CEA activity has been compared to that found in hepatic metastases from colorectal tumours and in normal adult lung. The antigen in the rheumatoid synovium has been shown to be more sensitive to perchloric acid and to isolate with a lower weight than that derived from the tumour and lung. Immunodiffusion studies with anti-CEA indicate that the CEA-like determinants in the rheumatoid synovium have partial identity with tumour CEA and that a significant proportion of them are associated with large molecular weight material. Production of an antiserum to these CEA-like components in the rheumatoid synovium should enable further identification of their relationship to tumour CEA and might allow a better judgement of whether or not they represent the expression of neoantigens in the disease.

Isoenzyme V of 5'-nucleotide phosphodiesterase (5'-NPD-V) is present in the peripheral sera of patients with hepatic metastases. A total of 122 patients underwent prospective serologic analysis followed by operation for primary tumors of the gastrointestinal tract and careful evaluation of the liver. A positive 5'-NPD-V assay was found in fifty-nine of sixty patients with liver metastases. A negative 5'-NPD-V assay was found in forty-three of sixty-two patients with no evidence of hepatic metastases. The accuracy of the test was 84 per cent, and the predictive value was 75 per cent. Serum 5'-NPD-V was abnormal significantly more frequently in patients with metastatic liver disease than were liver scans or carcinoembryonic antigen (CEA), alpha fetoprotein, serum glutamic oxalacetic transaminase (SGOT), and total serum bilirubin or serum alkaline phosphatase levels.

Extensive follow-up investigations were done in 1978 in 135 patients, most of whom had been operated for colo-rectal carcinoma of all stages in 1977. In 71% of the cases no or no sufficient postoperative control had been performed in the patients' own area. At the follow-up investigations 11 recurrences in the anastomosis, 10 of which were operable, 20 distant metastases, 1 simultaneous second carcinoma, 15 adenomas, partially with numerous atypical cells, 1 polyposis coli and 23 nonspecific granulomas of the anastomosis were detected. The Haemoccult test was positive in 3 of the 11 anastomotic recurrences. Only in cases of distant metastases were values of carcinoembryonic antigen clearly increased (greater than 5 ng/ml). These findings underline the necessity of intensifying the regular follow-up investigation in colo-rectal carcinoma.

The recent reports of the use of serum and tissue enzyme assays in primary diagnosis and then in following the course of the disease have been reviewed. These include use of bone marrow acid phosphatase, isoenzymes of both acid and alkaline phosphatase, LDH5/LDH1 ratios, sialyltransferase and the combination of carcinoembryonic antigen with serum enzyme assays to help in prediction of the occurrence of hepatic metastases.

An immunoperoxidase study of the presence of carcinoembryonic antigen (CEA) in primary cancers of the urinary bladder, metastases to the bladder, non-malignant diseased bladder, and normal bladder tissues revealed that approximately 10 percent of the urothelial carcinomas (transitional cell and squamous cell types) contained detectable quantities of this antigen. The other tissues were devoid of stainable CEA. It thus appears that the incidence of positive CEA by immunoperoxidase staining of formalin-fixed, paraffin-embedded tumour tissue sections is much less than the frequency of blood or urinary CEA elevations in patients with urothelial cancer.

The presence of calcitonin and of carcinoembryonic antigen (CEA) was studied in six cases of medullary carcinoma of the thyroid using an immunoperoxidase technique. In five cases the material was obtained surgically and in one at autopsy. Tissue from primary tumours as well as from metastases was studied. Calcitonin and CEA were identified within all the tumours studied, although their pattern of distribution and staining intensity varied both within the cells and within the tumour. Some parts of the tumour contained both CEA and calcitonin, while others stained positively only for one of these substances. In some parts of the tumour there was no positive staining for either substance. Within the cells, CEA showed a typical linear distribution along cell surfaces, while calcitonin showed a more even cytoplasmic distribution and the deposits were more granular. Normal tissue surrounding tumour deposits did not show positive staining. It is considered that cells of medullary carcinoma of the thyroid contain both calcitonin and CEA. Identification of CEA and calcitonin in tumour tissue can be used as a diagnostic aid to identify medullary carcinoma of the thyroid. Iit is considered that these substances are being produced by this tumour and can be used as tumour markers.

Plasma carcinoembryonic antigen (CEA) in nanograms per milliliter was assayed in 149 patients with benign and 567 patients with malignant disease. Elevated CEA level (greater than 5.0) was a good indicator of malignant disease but a poor screening test for cancer because of the high false-negative rate. Degree of elevation of plasma CEA level correlated with incidence of metastatic disease in patients with colorectal, gastric, and breast carcinomas, but no correlation was seen between CEA levels and status of lymph nodes in patients with localized disease. Patients with localized colorectal cancer, but elevated CEA levels before resection, had a 2.1-fold increase in the incidence of recurrence; however, this added to the prognostic value of Dukes' staging only when the CEA level remained elevated postoperatively. In 87% of patients with colorectal cancer, the CEA level was elevated at the time of recurrence, but a therapeutic value of reexploration for unexplained CEA level elevation was not confirmed.

The experience from the University of Minnesota with routine reoperations in cancers classified as Dukes' C suggests only a small minority of patients found to have asymptomatic recurrences will benefit from an additional operation. Also, morbidity and mortality will be significant. The presence of a rising carcinoembryonic antigen level following a potentially curative operation has been suggested as a more selective indicator for reoperation. Unfortunately, carcinoembryonic antigen levels are a far more sensitive indicator of hepatic metastases, the group usually not helped by operation. Patients with local-regional recurrent carcinoma of the colon and rectum--the group most likely to benefit from reoperation--often have normal carcinoembryonic antigen levels. The importance of patient selectivity for reoperation and the usefulness of the Astler-Coller staging system to define risk factors are stressed.

Serial plasma carcinoembryonic antigen (CEA) levels were determined in 84 patients with breast cancer who were receiving postsurgical adjuvant chemoimmunotherapy or adjuvant chemotherapy. CEA values were correlated with clinical status, scintiscans, alkaline phosphatase, LDH, and SGOT. CEA values greater than 2.5 ng/ml were considered abnormal. Thirty patients had normal serial CEA values; all remain disease-free. In 54 patients one or more abnormal CEA values were recorded; nine of 54 developed overt metastatic disease. Relapses occurred in four of 38 patients in whom values up to 5 ng/ml were recorded, in three of 14 patients in whom values up to 10 ng/ml were recorded, and in two of two patients in whom values greater than 10 ng/ml were recorded.

Preoperative and postoperative plasma carcinoembryonic antigen (CEA) levels in patients with colorectal carcinoma have been reported to correlate with tumour mass and prognosis. The erythrocyte sedimentation rate (ESR) has previously been reported to be elevated in most patients with metastatic carcinoma. In this study of 17 patients with advanced colorectal carcinoma and of nine patients who were disease-free more than three years after resection of their tumour, the plasma CEA and ESR levels demonstrated a close correlation, both in frequency and in degree of elevation, with the disease status. Of nine patients who were disease-free more than three years after resection of their colorectal carcinoma, all except one had plasma CEA levels of less than 20 ng/ml and an ESR less than 20 mm in one hour respectively. The incidence of plasma CEA more than 20 ng/ml and ESR more than 20 mm in one hour in the locally advanced and distant metastases groups, as compared with those patients in the more than three years group, was increased at a level of statistical significance (P less than 0.05). This study showed that the ESR, an inexpensive and simple estimation, may be as effective as the estimation of plasma level of CEA in monitoring the disease status of patients with colorectal carcinoma.
